What indicates a potential problem in database performance in Dynatrace?

A potential problem in database performance is indicated by changes in response time and failure rate. This is because response time measures how quickly the database processes queries, and an increase in this metric can signify that the database is struggling to handle requests efficiently. Similarly, an increased failure rate, which reflects the number of unsuccessful database queries, can indicate issues such as resource constraints, locking conflicts, or other underlying problems that affect the database's ability to function properly.

Monitoring both response time and failure rate helps identify not only performance degradations but also potential bottlenecks or operational issues that may require diagnosis and intervention. By closely observing these metrics, practitioners can gain insights into the overall health of the database and take proactive measures to ensure optimal performance.

Other factors, like the number of active users, trends in network traffic, or server configuration changes, may impact performance but do not directly indicate a database performance issue without correlating response times and failure rates.
